It transfers digital signals (NAMUR sensors/mechanical contacts) from a hazardous area to a safe area. The proximity sensor or switch controls a form C changeover relay contact for the safe area load. The normal output state can be reversed using switches S1 and S2. Switch S3 is used to enable or disable line fault detection of the field circuit. During an error condition, the relays revert to their deenergized state and the LEDs indicate the fault according to NAMUR NE44. A unique collective error messaging feature is available when used with the Power Rail system. 2 Features 1 3 4 6 2 5 13 15 12 9 10 7 14 11 8 KFD2-SR2-Ex2.W 1 2 OUT CHK PWR S2 S1 S3 I II Front view LED yellow: Relay output Ι LED red: LB/SC channel Ι LED yellow: Relay output ΙΙ LED red: LB/SC channel ΙΙ Switch S3 (LB/SC-monitoring) LED green: Power supply Removable terminals green Removable terminals blue Switch S1 (Mode of operation channel Ι) Switch S2 (Mode of operation channel ΙΙ) Release date 2016-09-13 11:47 Date of issue 2016-09-13 132960_eng.xml Technical data KFD2-SR2-Ex2.W 2 Refer to "General Notes Relating to Pepperl+Fuchs Product Information".

The fuse-protected power feed module can supply up to 150 individual devices depending on the power consumption of the devices. Collective error messages received from the Power Rail activate a galvanically-isolated mechanical contact. Power Rail UPR-03 The Power Rail UPR-03 is a complete unit consisting of the electrical insert and an aluminium profile rail 35 mm x 15 mm. To make electrical contact, the devices are simply engaged. Profile Rail K-DUCT with Power Rail The profile rail K-DUCT is an aluminum profile rail with Power Rail insert and two integral cable ducts for system and field cables. Due to this assembly no additional cable guides are necessary. Power Rail and Profile Rail must not be fed via the device terminals of the individual devices!
